Rare Earth Doped

The fluorescence and up-conversion spectral properties of Er3+-doped TeO2-ZnO and TeO2-ZnO-PbCl2 glasses suitable for developing optical fiber amplifier and laser have been fabricate and characterized. Strong green (around 527-550 nm) and red (around 661 nm) up-conversion emissions under 977 nm laser diode excitation were investigated, corresponding to 2H11/2, 4S3/2, ® 4I15/2 and 4F9/2 ® 4I15/2 transitions of Er3+ ions respectively, have beenobserved and the involved mechanisms have been explained. The dependence of up-converted fluorescence intensity versus laser power confirm that two-photons contribute to up-conversion of the green-red emissions. The novelty of this kind of optical material has been its ability in resisting devitrification, and its promising optical properties strongly encourage for their further development as the rare-earth doped optical fiber amplifiers and upconversion fiber laser systems.

High gain, rare-earth ions co-doped multicomponent phosphate glasses with different doped concentration ratio were prepared and investigated by means of absorption and fluorescence spectroscopy in order to investigate the influence of different doped concentration ratio on material optical properties. The main results showed that there was a strongest absorption at 980nm and saturated at 1530nm when Er3+and Yb3+concentration ratio was 4:1, which is the optimum ratio. It is also demonstrated that reaction and energy transfer mechanism between different ions in rare-earth co-doped system, which is significant for their interest in the fields of optical fiber amplifier and laser.
